SOAP was developed by Dave Winer, Don Box and others in the year 1998. The full-form of SOAP is Simple Object Access Protocol. It is a system of rules governing XML based messages which are used to encode the data in web service request and answer the message before it is sent over a computer network. They are independent of the operating system being used or it can also be used to send messages via a number of internet protocols which includes MIME, SMTP and HTTP.
Although there are many ways of prototype of messaging in SOAP, but the one which is most commonly used is the Remote Procedure Call pattern. In this type of pattern, the client computer sends a request message to the server; the server reacts instantaneously by sending a reply message to the client computer.
